"It is an impressive opera about real issues. The Nazis banned it and the premiere took place in Zürich. The cast is strong. Wolfgang Koch, always looking grizzled and dishevelled, is a powerful Mathis. Kurt Streit as Albrecht is really impressive both as actor and singer. The veteran Franz Grundheber is a convincing Riedinger, and Charles Reid a splendidly slimy Capito, Albrecht's adviser. Manuela Uhl's Ursula is expressive but a bit shrill ... The costumes are nearly all modern and drab, apart from Albrecht's magnificent cardinal's robes, on his first appearance only ... Despite the oddities of the production, the strengths of this performance outweigh the weaknesses".
